21 Claims.

This invention relates to maniiolding, and is a division of my copen'ding application Serial No. 335,402, filed January 28, 1929, which matured into Patent Number 1,957,405, May 1, 1934, and forms part of the invention described'and claimed therein. The present application concerns the manifolding pile or pack per se.

In the art of manifolding, it is frequently desired to simultaneously feed work sheets and carbon sheets which are of indefinite length, so that the writing process might be continuous. In

such work, to keep the several superposed strips in register longitudinally and transversely, it has been' proposed to provide the strips with marginal rows of holes and to provide on the writing machine wheels having pins for engaging in these marginal holes to feed the sheets. vide these marginal rows of holes in the carbon strips requires that they be passed through a printing press or similar machine equipped with punching devices. This processing of the carbon strips increases their cost and hence the cost of the supplies needed for performing the work. Yet, it is necessary to keep the carbon strips in substantial register with the work sheet strips, for otherwise they may gradually work outwardly of the pile in, the feeding operations, or be actually jogged outwardly during the return movement. of the carriage when used in a typewriter.

A feature of a portion of this invention claimed herein is the provision of a manifolding pile hav- 'ing the work sheet strips'provided with margins To pro- Figure 1 is a sectional side view of part of a carriage of a typewriting machine, showing the device of the present invention applied thereto,

extending beyond the side edges of the carbon sheet strips so that the carbon sheet strips need' tively narrow carbon strips of such width that their side edges are tangential to the pin-wheel feeding apertures in the work sheet strips whereby the pins engaging through said apertures may act as gages for the carbon strips and bring the carbon strips into desired lateral position-with relation to the work sheet strips should they tend to slip sidewise.

Other features and appear.

In the accompanying drawings, which show one form of the invention, that at present preferred-,--

advantages will hereinafter The manifolding pile of the present invention may be used with various machines and, to exemplifythe invention, is illustrated herein in the same connection in which it is illustrated in my said copending application, Serial No. 335,402, filed January 28, 1929, of which this is a division,

wherein there is shown a typewriting machine having a. platen III for supporting work sheet strips II and carbon sheet strips I! in position to be engaged by type bars l3 which, as indicated,

swing upwardly and rearwardly against the front face of the platen to imprint characters on the uppermost work sheet strip H by means of a ribbon i4 and to cause those characters to be duplicated on the under strips II by the carbon sheet strips I2, one of which is provided for each of the under work sheet strips I l. The platen i0 is mounted in a carriage I5 adapted to travel to and fro in letter-space direction. In the form shown,

the carriage slides'on a square shaft I 6 passing through the center of the platen I0 and serving to rotate the platen when it is rotated and h s e rear guide I! upon which it rides.

The carriage I5 has a paper table lia. at the introductory side of the platen for guiding work sheets thereto and the forward part of the table has an apron [5b which holds the work to the platen.

The work sheet strips ll usually contain 'a succession of printed forms having delineated spaces 18 'ln'which indicia is to be written. Due to the proximity and restricted area of the spaces l8, it is imperative that all the work sheet strips I i be maintained in accurate registration, so that inclicia written in the delineated space of one strip will be located entirely within the corresponding delineated space of the other strips.

To maintain this desired registration, it has previously been proposed that, as shown in the accompanying .drawings, the work sheet strips ll be provided with holes ll, arranged in succession forming rows extending longitudinally of the strips and at the side margin 2| thereof. The holes II are adapted to be engaged by pins carried by wheels 22 secured to the platen It so as to rotate therewith. In the feeding operation, the pins 2| being engaged with some 'of the holes I! advance the strips eoincidently with the rotation of the platen, and as the pins one after another engage succeeding holes at the introductoryside of the platen, due to their tapered ends 22, they bring the strips into accurate registration and positively advance all of the strips together without any-danger of slippage between them. The paper apron I5?) holds the work sheets close to the platen and the pin-wheel so that the pins will extend through the holes I. The paper apron llb is slotted at lie to permit rotation of the pinwheels without interference of the apron with the pins. I Were the carbon sheet strips l2 similarly provided with holes, they too would be held in the desired relation to the work sheet strips I I. But,

to thus prepare the carbon sheet strips it would be required that they be passed through a machine which would punch the holes in the side 'margins and this would add cost to the pack or roll of stationery.

To, avoid this, the present invention provides means for guiding and controlling the positions of the carbon sheet strips so that they are maintained in the desired location between the work sheet strips without requiring that they be provided with these rows of, marginal holes. 40

This is accomplished by the present inven-.

tion by accurately and positively guiding the carbon sheet strips by their side edges both at the platen and at a point at the introductory side of and close to the platen.

The means for accomplishing the last-named function in the form shown herein, comprises a frame 2 having-side plates ,2! between which are secured guide rods II over'which both the work sheet strips I! and the carbon sheet strips l2 ride, one strip engaging each rod. The frame and assume the most natural position for guiding the strips. In loading the machine, the strips II and II are led from a pack-P supported on a table or other convenient device and the strips areseparated with, one strip only passing over each rod 28.

In the form shown, the work sheet strips II are guided by directly engaging with their side edges 2| on inside surfaces of the plates 25, and

thusare kept in accurate alignment with each other. The carbon sheet strips i2, however, which, for reasons stated below, are narrower than the work sheet strips, engage with their side edges l2a against guiding blocks 22 placed between the rods 26 which lie above and below the'carbon strip [2. The guides 28 are each provided with a hole 22 to receive the lowermost.

I of the pair of rods and a semi-circular notch ill toreceive the upper rod.- The guide 2! is 7 This mount- 55 held in adjusted position by a set screw Ii carried by the guide and engaging the lowermost rod.

As stated, and as is customary, the work sheets are guided and held in accurate alignment at the platen by the engagement of the pins II on the pin-wheels 22 with the marginal holes I! in the work sheet strips. To guide the carbon sheets and prevent them from shifting trans versely at theplaten, the present invention makes the carbon sheet strips I2 of such width or places the pins 2| in such position (according to which change is most convenient or'de sirable) that the side edges l2a of the carbon sheet strips l2 are in position to be engaged by the inside edges 2la of the pins 2|, as shown in Fig. 3. The pins 2i thus hold the carbon sheets [2 captive between the work sheets at the platen and should a carbon'sheet tend to skew or to creep sidewise during the rotation of the platen, the pins 2i will cam or guide them back into position.

Of, course, it is not absolutely essential that the distances between the side edges l2u of the carbon strip andbetween the inner edges Ila of the pins be absolutely the. same, but when used with the mechanism described it is preferable that they-be substantially the same, leaving only such clearance between the edges I21: of the carbon strip and the edges 2 la of the pins as is necessary or expedient to compensate for variations in the manufacture of the parts and paper. The space, however, between the side edge i2a of the carbon strip and the inner edge 2la of the pin must not be so great as to to a great extent by the provision of the guide.

blocks 28 for the carbon sheets at the introductory side of the platen and taken together with the side edges of the pins 2| have been found in practice to keep the carbon sheet strip well confined and against lateral movement relatively to the work sheet strips.

After the strips Ii have been fed around the platen by the pin-wheels 22, they are stripped from the pins by a plate II at the delivery side of the platen. The plate II has slots 22 through which the pins pass to lift the paper from the pins as the platen is rotated, the paper being forced to travel upwardly along the plate.

I The carbon and work sheet strip controlling means of the present invention is extremely adva'itageous, particularly in connection with automatic or telegraph typewriters which frequently operate for relatively long periods without being observed by an operator.

. The frame 2|, instead of being arranged so that edges Ila of the carbon sheet strips may be obtained by either cha ging the positions of the pins or making the carbon sheet strips wider, that is, changing the machine or the pack of stationary. Accordingly, the present invention contemplates and embraces not only the mechanism disclosed and claimed in my copending application aforesaid, but also a manifolding pile' claimed per se herein.
